CRANE FOR CARRYING LADIES.

Speciiieaton of Letters Patent.

Patented Sept. 3, 1907.

Application filed March 9,1906. Serial No. 305,107.

To all whom it may concern:

Be it known that I, CLARENCE L. TAYLOR, of Alliance, in the county ofStark and State oi Ohio, have invented certain new and useiulImprovements in Cranes Vlor Carrying Ladles; and I dohereby declare thefollowing to be a lull, clear, and exact description oi the invention,such as will enable others skilled in the art to which it appertains tomake and use the saine.

My invention relates to an improvement in cranes lor carrying ladles,the object being to minimize the danger due to lneaking oi the hoistropes or chains, and it consists in a novel arrangement of drums forcarrying two sets ol ropes or chains supporting the ladle carrying bar,each being secured to its own drum, the several drums being gearedtogether so as to move in unison.

My invention l'urther consists in the parts and combinations ol parts aswill be more lully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in iront elevation ot abridge showing a trolley with my improved hoisting mechanism thereon.Fig. 2 is a view in plan ol the trolley and Fig. 3 is a view intransverse section of the bridge showing the main and auxiliary trolleysin elevation.

1 represents a traveling bridge adapted to travel on the rails 2extending lengthwise the mill or foundry. This bridge may be ot' anyapproved form or construction, and is provided on its upper surface withthe rails 3 on which the main trolleyll travels. This main trolley ismounted on wheels 5, two of which are propelled by the motor 6, thearmature shaft el which has a small pinion 7 meshing with a largerpinion 8 on shalt 9. This shaft carries at its oppositel end the smallpinion 10 which meshes with pinion l1 on shait 12. This shalt extendsacross the trolley and is provided with two pinions 13 each oi whichengages a pinion 14: fast to a track wheel 5. By rotating the motor thetrolley will be propelled lengthwise the bridge. The body or traine ofthis trolley projects downwardly and ,ontwardly at its opposite sides asat 14a, so as to overhang the bridge girders l as clearly shown in Fig.3. Each overhanging section of the iraine carries two double drums l5and 15L and 16 and 16, the axes of .which are parallel with the bridgegirders, the double drum 15 and 16 being located with their axes in thevertical planes o' the centers oi the wheels 5 carrying the trolley,while the outer drums 15n and 16 are in planes wholly outside the bridgegirders.

Each drum l5 15LL 16 and 16fL is provided centrally with a toothed gear17, the two gears 17 on the drums at each side or rather of each pair ofdrums, being in mesh so that a motion imparted to one drum 15 or 16'toothed wheel 25 on shai't 26.

`similar to shaft 26.

will transmit motion in the opposite direction to its companion drum 15or 16.

Located on the trolley is the inain. hoist motor 18 the armature shaltof which, carries pinion 'I9 ineshin with pinion 20 on a shaft carryingthe small pinion 2l. Pinion 2l. is in mesh with pinion 22 tixcd on shalt23, eX- tending across the trolley parallel with the hoisting drums, andcarrying pinion 2li meshing with the large Wheel 25 is in mesh wi thtoothed wheel 27, the latter being ol the saine size as wheel 25, and issecnrcd on a shalt 28, in all respects Each shaft 26 and 28 has aeentrally located pinion 29 the pinion 2) on the shait 2S engaging thepinion 17 carricd by the drinn l5 at one side oi the trolley, while thepinion 2S) on shai't 26 engages the pinion 17 on drum 16 at the otherside ol the trolley. lVith this motor 18 and the arrangement ol' gearsas above described, it will be seen that when the motor is actuated, theiour double drums 15, l5, 16 and 16" will be actuated in unison and atthe same speed, the two inner drums 15 and .16 rotating in oppositedirections, while the outer drums 151L and 16, oi each pair, rotate in adirection opposite the direction oi rotation oi its companion drum.

Each section of cach double inner drinn 15 and 16, has a rope or chain3() secured thereto and adapted to be wound thereon and unwoundtherefrom.

The two ropes or chains irorn each ot the double inner drums l5 and 16at each end oi' the trolley, pass down outside the main girders andaround double sheaves 31 located at cach end oi the ladle carrying bar34, but on opposite sides ei the bar, while the two ropes or chains fromeach oi' the double outer drums l5" and .16 at the opposite ends of thetrolley, pass down and around double sheaves 3l.. lhosc eight ropes orchains alter passing around the sheaves 3l on the ladle carrying bar 34,pass upwardly and around double sheaves 32 mounted on the shaits ol theouter drums l5*L and 16" and then down and secured to the opposite endsof the levers 33 pivotally secured to the upper surface ol' the ladlecarrying bar 34. With this arrangement it will be seen that the ladlecarrying bar lill is supported by two independent sets oi ropes orchains at each end, either set oi which, will he capable of sustainingthe load in the event any one rope or chain should break, thusminimizing the danger due to the breaking oi a hoist rope or Chain.

By having the double drums at cach end coupled by intermeshing gears,and connecting the two sets oi' drums to a single source oi` power, thedrums necessarily move in unison at the saine speed and in their properrelative directions to wind and unwind the hoist chains.

The bridge girders are provided on their lower llanges with the rails 36on which the auxiliary trolley 37 travels. This trolley carries a drumarranged with its axis at right angles to the direction oi travel ot thetrolley and its hoist chain 3S is employed l'or tilting the ladle ortransporting tools and material ol any kind.

It is evident that many slight changes might be resorted to in therelative arrangement oi parts herein shown and described withoutdeparting from the spirit and scope of my invention hence I would haveit understood that I do not wish to contine myself to the exactconstruction of parts shown and described, but,
